Estimation of Optimal Rubber Content

FIGURE 2.3 Stresses oC0m and Cb of RubCon depend on amount of rubber. (Reprinted from O. Figovsky and D. Beilin, Building Materials Based on Advanced Polymer Matrix Review, J. Scientific Israel Technological Advantages 10, no. 3 (2008) 1-119. With permission.) 

The analysis of the obtained data shows that the optimal content of rubber in the composition is from 8.5 to 10.5 mass%. Rubber content of less than 8.5 mass% causes discontinuance of the film structure of the polymeric matrix and pore formation, while more than 10.5 mass% provides an unstable inhomogeneous structure of the mixture during formation.
